or less in the same spot indefinitely, food will be brought to
them. And that is what happens. As a rule they do not even ad-
-vance to meet their parents when they see them bringing food, even
one step. Usually, also, they are pretty capable of taking care
of themselves before they assimilate the fact of my being in
some way hooked up with the food supply. Thus Brownie's special
charge, for the first time, on the 14th., came to me with his pa-
rent.
Nova feeds her bird (or birds) suet extensively.
Rhody continues to do all the regular things appropriate
to the occasion, following out his recent trend of displaying
less when given a mouse. (I.e.: less often displaying). Rough-
ly, now, I should say that he goes through the ritual about half
the time. He still roosts in the oak west of the house at night,
uses nest 5-36 to rest in, adds a little to it now and then, re-
tains his interest in the magpies, likes to preen in the cage for
many minutes at a time, continues to lay unsuccessful siege to the
lizard resident there, investigates the cause of disturbances
amongst the other birds and inspects all new creations of mine in
and about the property.
About 5:30 P.M. on the 14th. I was letting the magpies reach
through the wire netting for pieces of meat held in hand. Rhody,
seeing a good opportunity to observe them more closely, flew up
to a handy perch and sat a foot from my hand watching intently,
with bulging eyes and skin colors fully displayed, crest raised.
It has been noted herein that this skin is of crepe-like texture, b
but that it can be stretched out smooth: "tightened up". This
was very noticeable on this occasion. He did not attempt to
peck either magpie, but kept his bill pointed at one or the other
of them as they moved about, and "popped".
He looks directly at an object in which he is intensely in-
terested most of the time, although he may use first one eye and
then the other, but not on this occasion.
This "pop" is a single snap of the beak, not often heard. IT
is not a click, but a rather resonant pop.

Gopher-snake eats
mouse. Julio caught a gopher-snake at the kitchen door and caged him
temporarily. This creature will be used to amuse Rhody in front
of the movie camera (I hope). I gave him a live mouse. He was
awkward and slow in catching it, but when he once had a grip on
it, with lightning rapidity crushed it between folds of his body--
not in his "coils"--retaining his head-hold at the same time.
He uses this fold as a "hand" to hold the mouse while he is try-
ing to push his mouth over the mouse's head. He continues to hold
the mouse in this way until it is fairly well down his gullet.
From the time he got his first teeth on the mouse until it was
about one foot on the way down, about 15 minutes elapsed.
Rhody as usual all day, including adding to nest 5-36.
Length of Rhody. When he stretched out in one of his spread-eagle summing poses
by my chair in which he lies flat on his belly, with tail, neck
and bill all flat on the ground and in a straight line, I marked
his two extremities with matches stuck in the ground. When he
got up, the interval was measured and proved to be 24 3/4 inches
(628 mm.). (Hoffmann: 20 to 24; Pearson in "Birds of America: 20
to 24; Dawson: 21 to 25. Rhody, then, would appear to be above
the average and near the upper limit).
